Description
Product Overview
The 1756-A13 is a standard 13-slot modular backplane chassis engineered by Allen-Bradley (Rockwell Automation) for the robust ControlLogix PAC platform. Serving as the mechanical and electrical spine for localized or distributed automation systems, this open-style rack houses and interconnects multi-tier CPUs, communication cards, and specialized I/O modules. Possessing a substantial frame with a net physical weight of 1.90 kg (4.2 lbs), this chassis provides rigid, vibration-resistant alignment and high-current power distribution across its high-speed integrated backplane bus lines.
Key Advantages
- High-Density 13-Slot Architecture: Provides expansive hardware capacity, allowing engineering teams to cluster multiple processors, network bridges, and high-density I/O configurations in one central zone.
- Multi-Rail Voltage Support: Features advanced internal bus tracks capable of handling combined current demands across 1.2V, 3.3V, 5.1V, and 24V DC lines to power complex modular setups safely.
- Heavy-Duty Ground Isolation: Utilizes dual-tier grounding terminations (supporting up to 8 AWG functional ground wires) to safely block electromagnetic interference and transient voltage spikes.
- Rugged Structural Frame: The 1.90 kg open-style body is built from premium materials to handle the cumulative weight and heat dissipation of up to 13 heavy industrial modules without warping.

Quick Installation Tips
- Enclosure Selection Strategy: Because this is an open-style chassis with no internal protective casing, you must mount it inside a closed control cabinet meeting a minimum dimension profile of 24 x 30 x 8 inches to ensure full safety from airborne debris.
- Dual Ground Bonding: Connect a heavy 8 AWG wire to the dedicated functional ground stud to reduce high-frequency electrical noise, and link a 14 AWG wire to the protective ground terminal for human safety.
- Power Supply Positioning: Anchor a compatible 1756 power supply module directly onto the leftmost structural mounting position of the 1.90 kg rack before sliding the other ControlLogix cards into their slots.
Technical FAQs
Q1: Can I insert a processor module into any of the 13 slots on the 1756-A13?
A1: Yes. The ControlLogix backplane architecture is entirely peer-to-peer and slot-independent. Unlike older PLC architectures, a CPU, communication card, or I/O module can be placed in any available slot from 0 through 12 based on your layout preference.
Q2: Why does the technical data sheet list multiple backplane current ratings?
A2: Different generations of ControlLogix modules draw power from different internal voltage rails. The 1756-A13 backplane features independent circuits to safely provide 1.2V, 3.3V, 5.1V, and 24V DC current levels simultaneously from the main power supply to the individual card sockets.
Q3: How does the maximum power dissipation rating affect thermal planning?
A3: The chassis itself radiates a maximum of 5.4 Watts of heat into the panel environment. When designing your cabinet ventilation or air conditioning loops, remember to add this base chassis heat value to the total calculated heat loss values of all 13 installed modules.
